2 Safety measures and instructions
Safety measures for work on the electrical system
• Disconnect the battery when repairing the charging circuit to prevent accidental short circuits.
• Before removal, disconnect the cable from the negative pole (–) and then from the positive pole (+).
• Do not disconnect the batteries when the engine is running.
• Connect the negative battery pole to the ground and the positive pole to the “B+” alternator output. The opposite connection
would destroy the whole semiconductor equipment.
• When starting using an auxiliary external power supply, do not disconnect this power supply until the machine battery is con-
nected. Pay attention to the starting voltage of the auxiliary external power supply (for 24 V).
• Do not put the alternator into idle operation, i.e. with adisconnected wire from the “B+” terminal and connected “D+” terminal.
• Do not check the presence of voltage in the wire by sparking against the machine frame.
• Do not perform any activities generating sparks.
• Use protective rubber gloves and eye protection when handling batteries.
• Protect your skin and clothes against being splashed by the electrolyte or lead particles.
• In case of eye contact with the electrolyte, immediately ush the aected eye thoroughly with running water for several minutes.
Then, seek medical treatment as soon as possible.
• If the electrolyte comes in contact with skin or clothing, remove the clothes, immediately wash the aected areas with soapy water
or asolution of baking soda and water and seek medical treatment.
• In case of ingestion of electrolyte, drink the maximum possible amount of milk, magnesium oxide dissolved in water or at least
water and immediately seek medical treatment.
• Never ll the cells with distilled water, unless it is followed by work with the machine or recharging outside the machine. It would
otherwise cause excessive battery self-discharge.
• Never ll up the acid (H

SO

)!
• Do not turn over the batteries to avoid electrolyte owing out of the degassing vents.
• In case of acid (electrolyte) spillage, wash the aected area with water and neutralize with lime.
• The battery charging process releases hydrogen, which forms an explosive, easily combustible mixture with air. Do not smoke or
use open ame or lights in the vicinity.
Welding work on the machine
• Before performing welding work on the machine using an electric arc, disconnect all elements containing semiconductors from
the electrical system, including the machine electronics:
- ground the power supply as well as the repaired machine,
- protect the power supply against moisture,
- place the ground terminal in close proximity to the weld joint,
- When performing welding work on suspended parts or machine, it is necessary to prevent current from reaching the lifting
equipment by insulating the point of current transition or using non-conductive slings (hemp rope).
Sealing
• Use new seals for all installation.
• Seal kits are obtained as spare parts.
Tightening torques
• In order to apply the correct tightening torque, use atorque spanner.
• Fastening screws and nuts of used quality shall be tightened according to the respective tables.
• The screw quality is indicated on the screw head.
• Dierent tightening torques are specied in the respective chapters.
• Threaded joints of hydraulic circuits shall be tightened according to the tables.
• The presented tightening torques apply to non-lubricated threads.
• Only use new self-locking nuts.
